We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary systems with component masses between 3 and 20M. Optimally oriented binaries with distances up to 1 Mpc could be detected with efficiency of at least 90%. We found no events that(More)
OBJECTIVE To review all cases of cesarean section in the primigravid mother delivered at the Riyadh Armed Forces Hospital between January 1996 and December 1997. To determine its incidence, describe the clinical indications, outcome and highlight areas of improvement in an attempt to reduce the rate of cesarean section. METHODS Retrospective case record(More)
We place direct upper limits on the amplitude of gravitational waves from 28 isolated radio pulsars by a coherent multidetector analysis of the data collected during the second science run of the LIGO interferometric detectors. These are the first direct upper limits for 26 of the 28 pulsars. We use coordinated radio observations for the first time to build(More)
